Cost Per Conversion

Cost per conversion (CPC or CPCon) is a term used in online advertising to refer to the total cost paid for an advertisement in relation to the success in achieving the goal of that advertisement. Cost per conversion is the ratio of the number of advertisement views and the number of successful conversions (purchases, signups, participation or whatever the objective of the advertisement is) resulting from those ad views.

Cost per conversion is the same as cost per acquisition. We use CPA instead of CPC because CPC is more commonly used to refer to cost per click.
